      J. Liq. Chromatogr. Relat. Technol. 37, 2872-2881 (2014). 2D-HPTLC of 17 alpha-ethinylestradiol on RP-18 with methanol – acetonitrile – water 2:2:1 in the first direction and cyclohexane – butyl acetate – methanol 8:6:1 in the second direction, both over 70 mm. With the grafted method both plates were combined in a 2D separation. Detection by dipping into a mixture of sulfuric acid (98 %) and water (1:49), followed by heating at 110 °C for 10 min. Compound was also detected using a yeast estrogen screening assay using the strain Saccharomyces cerevisiae BJ3505.

      J. Planar Chromatogr. 28, 268-273 (2015). HPTLC of astragaloside IV (1) and formononetin (2) in dried roots of Radix astragali (Astragalus membranaceus) on silica gel with petroleum ether - n-butanol saturated with water - glacial acetic acid 7:4:8. Detection by spraying with 10 % sulfuric acid ethanol solution, followed by heating at 105 °C. Quantitative determination by absorbance measurement at UV 254 nm. The hRF values for (1) and (2) were 43 and 75, respectively. Linearity was in the range of 1-10 μg/mL. The intermediate precision was below 0.4 % (n=6). Recovery ranged between 98 and 99 %. Compared to HPLC, HPTLC offered a rapid, economic, and sensitive method for detection of compounds.

      Thin layer chromatographic resolution of some ?-adrenolytics and a ?2-agonist using bovine serum albumin as chiral additive in stationary phase
      P. MALIK, R. BHUSHAN* (*Dep. of Chem., Indian Inst. of Technol. Roorkee, Roorkee-247667, India, rbushfcy54@gmail.com)

      J. Chromatogr. Sci. 56 (1), 92-98 (2018). TLC for direct enantiomeric resolution of the racemic β-adrenolytics bisoprolol (1), atenolol (2), propranolol (3), salbutamol (4) and carvedilol (5) by TLC using bovine serum albumin (BSA) as chiral additive in the stationary phase and with different compositions of simple organic solvents without buffer or inorganic ions. Systematic investigation of the effect of variation in pH, temperature, amount of BSA as the additive, and composition of mobile phase on resolution. Detection by exposure to iodine vapors. The five entantiomers were separated in the elution order (1), (2), (3), (4), and (5). The LOD was 0.7, 1.2, 0.8, 1.6 and 0.9 μg/zone for (1), (2), (3), (4), and (5), respectively.
